Affiliate commission is the payment an affiliate marketer earns for referring customers to a merchant’s product or service.
The core formulas:
Commission Earned = Sale Amount × Commission Rate
Monthly Earnings = Monthly Conversions × Average Commission
Earnings Per Click (EPC) = Total Earnings / Total Clicks
Conversion Rate = Conversions / Clicks × 100
What each variable means:
- Commission Rate — the percentage of the sale price paid to the affiliate (typically 3–50%)
- Monthly Conversions — number of referred sales or sign-ups in a month
- EPC — a critical benchmark showing how much each click is worth; use this to evaluate traffic sources
- Conversion Rate — how many of your referred visitors actually buy
Worked example: You promote a $150 online course with a 40% affiliate commission. Your blog sends 3,000 visitors/month and converts at 2%.
Conversions = 3,000 × 0.02 = 60 sales Commission per sale = $150 × 0.40 = $60 Monthly earnings = 60 × $60 = $3,600/month EPC = $3,600 / 3,000 = $1.20 per click
Typical commission rates by category:
- Physical products (Amazon): 1–10%
- Software/SaaS: 20–40% recurring
- Online courses: 30–50%
- Financial products: $50–$200 flat per lead
- Web hosting: $50–$150 flat per sale
Recurring commissions (SaaS products) are the most powerful — a single referral can earn you commissions every month for years without additional effort.
